Every ramp-up to every election since blogging has been in existence has seen the blogosphere explode with the usual 'Republicans are anti-science' hype while whitewashing Democrats who do the same thing.

Well, I agree - not about taxes, about politicians being irrational. Scientists can change their minds but politicians rarely do. When Steven Chu became Energy Secretary, for example, he was an anti-CO2 zealot but since that time climate scientists have discovered there are multiple drivers in climate and weather and Chu has embraced the Keystone XL pipeline, which will make oil cheaper and better for the environment due to less import footprints - that's good for poor people and for mitigating the power of terrorist-exporting dictatorships, which are things both sides agree on.

So progressives have seen the light on one anti-science position; that any green energy is worth throwing money at - but as soon as one bit of crackpottery dies another takes its place. That brings us to BPA. If you read environmentalist activist hysteria about bisphenol A (BPA) it's killing babies. You're not in favor of dead babies, right?

No, none, but Greenpeace says it is. If they're qualified to write IPCC reports, they're qualified to use scare tactics to get donations from concerned mothers. And they have other advocacy groups like Environmental Working Group doing junk 'gotcha' studies with tiny samples that have convinced journalists who need something to write about to do good works (instead of, you know, journalism) by banning BPA.

Anti-science mentalities go both ways. If you don't believe it, I know how you vote.

It isn't ethically or intellectually more superior to believe an old guy created the universe than it is to believe vaccines cause Autism, yet those are clearly anti-science beliefs that skew right and left. How many bloggers or NY Times editorials complain Democrats are anti-science due to a lot of Democrats being anti-vaccine? If Texas Gov. Rick Perry endorses banning BPA using his awesome scientific method, is he still anti-science or is he suddenly as smart as Democrats in California? If their claim is we should be conservative and ban BPA because we don't know it is safe, well, that is downright ironic.

The FDA has not issued tighter restrictions on BPA because they looked at the data. Nor has WHO, for the same reason. Environmental advocates contend that Evil Industry can't be trusted to do research (yet Greenpeace can) but no taxpayer-financed research has found concerns with BPA either.

Instead, activist groups are using the same approach progressives criticized when the US Chamber of Commerce thwarted regulatory responses to climate change. It's also the modus operandi for anti-vaccine crusaders.

Actually, it is considered an additive because it lines cans, containers, etc. The problem with irrationally replacing something with no risk is it can be replaced out of necessity and rushing with something different, but not better. MTBE, PBDEs, you name it, when some irrational group gets a politicians ear about change and the media hypes it up, the problem gets worse.

Breast feeding a baby is best but not all mothers can do that so the alternative is bottles and stuff in cans and those can be harmful if they are not lined.

BPA is under constant study because exposure is so prevalent and it is difficult to know what impacts a tiny body - but he is saying he recognizes that without BPA kids are exposed to much worse.
